Radio GPS Hyundai IX35

Hello, very good! I want to change the radio that comes standard in my Hyundai Ix35, and I would like to put one that carries GPS, tactile screen, TDT, etc ... but I have several doubts, one is like knowing if my car carries Can Bus and the other is like disassembling the original radio, to mount the GPS with the function of seeing the back image back. If someone knew something about this issue, I would appreciate it, anyway grace ....
